I definitely understand the mentality of no invasions. They've a history of being messy, contentious, and overwhelming to post in.
However, we did create this faction specifically to take the fight to the Sith ICly, and now that we're major, we won't be able to avoid other factions invading us. So invasions seem to be the cards for us at some point.
So whether story-based like Braith suggested, or whether we implement a completely different game mechanic, like the BYOO one suggested in Rhys' blog post, this is our shot to make them what we want them to be and make them fun again!
There are no bad ideas here.
